RE: NGVAmerica Comments on the State of Arkansas Volkswagen Environmental Trust Draft Beneficiary Mitigation Plan
Dear Mr. Montgomery and Ms. Treece:
Natural Gas Vehicles for America (NGVAmerica), the national trade association for the natural gas vehicle industry, respectfully submits the following comments to the Arkansas Department of Environmental Quality (ADEQ) on the State of Arkansas Volkswagen Environmental Trust Draft Beneficiary Mitigation Plan (Plan). These comments are in addition to the NGVAmerica comments submitted on March 23, 2017 (attached) regarding NGVAmerica’s recommendations on how states can best use the Environmental Mitigation Trust (EMT or Trust) funds that each state will receive as part of the Volkswagen (VW) diesel emission settlement.
The VW EMT funds provide an extraordinary opportunity for Arkansas to cost-effectively transition to cleaner vehicle fuels with lower vehicle emissions. Whether regional trucking, waste hauling, medium duty delivery, transit or school buses, commercially-available natural gas vehicles offer the best solutions for addressing the goals of the EMT, delivering the most nitrogen oxide (NOx) emission reductions for the least cost.
Arkansas’ draft VW Plan reflects a good understanding of the goals of the EMT, especially the primary goal of achieving significant and sustained reductions of NOx emissions. In reviewing the following secondary goals, it is evident that ADEQ has focused on the important outcomes that the VW funding can accelerate for Arkansas:
Reductions in emissions of other pollutants (PM & GHG);
Spurring private investment in alternative fueling infrastructure and vehicles;
Creating jobs by increasing alternative fuel production in AR; and
Establishing alternative fuel corridors along interstates to link to corridors established in other states.
The specific three programs that ADEQ has identified as funding priorities for its $14.65 million include:
CNG School Bus Pilot Program (60% of AR VW funding) - $8.78 million for CNG natural gas school buses
Light Duty Electric Vehicle Infrastructure Rebate Program (15%)- $2.2 million rebate program for EV charging stations
Statewide Alternative Fuel Grant Program (25%) - $3.66 million for a state-wide grant program for low-NOx CNG engines/vehicles or electric vehicles
As a general comment and request, NGVAmerica asks that liquefied natural gas (LNG) and renewable natural gas (RNG) also be allowed in addition to compressed natural gas (CNG). LNG is a very viable option in the heavy-duty truck and bus sector (also rail, marine, mining and other heavy-duty applications), and RNG actually enables natural gas vehicles (NGVs) to be the cleanest available technology due to taking emissions from the waste produced through animals, plants, food and waste water, that would otherwise go into the air.

With regard to the CNG School Bus Pilot Project, a similar effort in Colorado has significantly increased the numbers of
CNG school buses in the state, thereby reducing emissions, noise and cost for students and school districts. The average
cost for an eighty-passenger school bus has been about $150,000 in that program, and so Arkansas with the stated desire
to have cost sharing should be able to fund almost 60 buses at a 50% cost share for the $8.78 million. It should be noted
that Class A, C and D CNG buses are currently available to meet the specific needs of school districts.
EV fueling infrastructure continues to be funded through several Federal and state programs, and it is NGVAmerica’s
position that if fueling infrastructure needs to be developed for any of the types of alternative vehicles, funding should
be secured as part of private-public partnerships. Using the funding in this way will encourage additional economic
development in the state and increase the availability of stations for future deployments.
The proposed Statewide Alternative Fuel Grant Program will encourage the growth of NGVs and EVs, helping achieve the
goals of the ADEQ VW Plan. NGVAmerica asks ADEQ to consider a funding strategy similar to that proposed in Colorado’s
Draft VW Plan that effectively incentivizes all alternative vehicles at the same percentage (25% of the total cost of the
vehicle for private industry and 40% for the public sector) and stresses that projects that are ready now to reduce the
most NOx for the funds expended will be given priority (new Argonne Lab AFLEET tool has updated emissions data).
NGVAmerica applauds the State of Arkansas for recognizing the value of natural gas vehicles in accomplishing the State’s
economic and environmental goals while using an important Arkansas fuel. We welcome the opportunity to meet with
you to provide further information and analysis on the economic and environmental benefits of natural gas vehicles in
Arkansas. Please contact Jeff Clarke, NGVAmerica General Counsel & Director Regulatory Affairs at 202.824.7364 or
[email protected], or Sherrie Merrow, Director, NGVAmerica State Government Advocacy at 303.883.5121 or
[email protected] to set up a meeting and for additional information.
Sincerely,
Daniel J. Gage President
Summary of NGVAmerica’s Recommendations for EMT Funding
Provide a larger incentive and greater overall funding for medium- and heavy-duty engines that deliver greater NOx reductions than currently required for new vehicles and engines
Target funding for technologies that have demonstrated the ability to deliver actual lower in-use emissions when operated in real-world conditions
Provide the highest level of funding to applications that produce the largest share of NOx emissions (in most regions this means prioritizing for short-haul, regional-haul and refuse trucks)
Prioritize funding for commercially available products that are ready to begin
Prioritize funding for clean vehicles rather than fueling infrastructure
Scale funding to incentivize the cleanest engines available
Ensure that funding incentivizes adoption by both public and private fleets
Accelerate the funding in the early years to maximize the NOx reduction benefits
Because the EMT was created for NOx pollution associated with non-compliant diesel vehicles, the funding should be set aside for clean, alternative fuel vehicle projects that focus on maximizing NOx reduction for the funds spent

Natural gas medium- and heavy-duty engines provide
unmatched reductions of smog-forming emissions of nitrogen
oxides (NOx). In 2015, a revolutionary natural gas engine
was certified by the U.S. Environmental Protection Agency
and California Air Resources Board to a level 90% below the
EPA’s current exhaust standard and 90% below the cleanest
diesel engine. A truck with this engine has an emission profile
equivalent to that of a heavy-duty battery electric truck.
Natural gas vehicles (NGVs) are transforming the medium- and heavy-duty transportation sector.
Allocating funds to deploy low-NOx natural gas vehicles provides the best way to deliver immediate and cost-effective NOx reductions and
air quality benefit. Nearly 40% of Americans are exposed to unhealthful levels of ozone and particulate pollution. Volkswagen’s $2.9 billion
Environmental Mitigation Trust fund provides each state an incredible opportunity to make an immediate and tangible impact on air quality
by targeting medium- and heavy-duty vehicles, the leading source of these toxic air contaminants in almost every metropolitan area.
The calculations shown below assume the deployment of the cleanest commercially available model for each application. Funding natural gas vehicles will lead to the largest total reduction in NOx emissions.

Volkswagen Diesel Settlement Funding Opportunity
Compared to Diesel:
Currently, natural gas prices can
be $0.75 to $1 or more lower than
diesel at the pump, with a firm price
advantage expected to remain for
decades as shown in the chart above.
Beyond the fuel-price differential, the
pump price of natural gas remains
relatively stable for two reasons. First,
it is domestically sourced. Second, the
commodity cost of natural gas only
makes up 23% of the pump price so
price fluctuations have minimal impact.
In contrast, approximately 60% of the
price of diesel fuel is impacted by
the market cost of crude oil, which
is largely sourced from politically
unstable, high-conflict regions. When
crude oil prices increase, diesel prices
follow suit which can lead to significant
swings in a fleet’s fuel costs.

March 23, 2017 Mr. William K. Montgomery Ms. Tricia Treece Arkansas Department of Environmental Quality 5301 Northshore Drive North Little Rock, AR 72118-5317 RE: NGVAmerica Comments on the Volkswagen Diesel Emissions Settlement and the Environmental Mitigation
Trust Implementation for the States Dear Mr. Montgomery and Ms. Treece: Natural Gas Vehicles for America (NGVAmerica), the national trade association for the natural gas vehicle industry, respectfully submits the following comments on how the Arkansas Department of Environmental Quality (ADEQ) can best use the Environmental Mitigation Trust (EMT or Trust) funds ($14.6 million) that the state will receive as part of the Volkswagen (VW) diesel emission settlement. The VW EMT funds provide an extraordinary opportunity for Arkansas to cost-effectively transition to cleaner vehicle fuels to lower vehicle emissions. Whether regional trucking, waste hauling, medium duty delivery, transit or school buses, commercially available natural gas vehicles offer the best solutions for addressing the goals of the EMT, delivering the most nitrogen oxide (NOx) emission reductions for the least cost.
The following pages outline key facts related to vehicle emissions, total cost of ownership, and current availability,
as well as NGVAmerica's recommendations on how EMT funds should be allocated.
The Need to Take Meaningful Action Today
The funding available through Volkswagen's Environmental Mitigation Trust comes at a time when it is critical to
address transportation emissions. The American Lung Association's "State of the Air 2016" report found that air
pollution continues to be a pressing concern with more than half of all Americans—166 million people—living in
counties where they are exposed to unhealthful levels of ozone and particulate pollution.
Medium- and heavy-duty on-road vehicles are the number one source of ozone-forming emissions of nitrogen oxides
(NOx) in almost every metropolitan region in the U.S., therefore there is considerable opportunity to develop and
deploy funding programs that make an immediate and tangible impact on air quality and related public health issues.
Approximately 50% of Americans live in
areas with air that is unhealthy to breathe
Medium- and heavy-duty vehicles are the #1 source

Sustainable, Responsible, Available: Natural Gas Vehicles
Today's natural gas vehicles (NGVs) are proven technologies that can uniquely, immediately, and cost-effectively
transform our nation’s medium- and heavy-duty transportation sector. The advantages of natural gas as a
transportation fuel include its domestic availability, widespread distribution infrastructure, low cost, and inherently
clean-burning qualities.
In these comments NGVAmerica presents the compelling reasons that states should prioritize funding for NGVs to
maximize the impact of the available funding. As your organization is aware, the EMT was set up to fund projects that
make an impactful reduction on NOx emissions to mitigate the excess emissions currently in our air from the non-
compliant light-duty diesel vehicles VW sold. NGVAmerica strongly believes that NGVs are the best solution to meet
the core goals put forth by the Volkswagen EMT funding. NGVs are:
❖ Key Point: Today’s natural gas medium- and heavy-duty engines provide unmatched reductions of smog-forming emissions of nitrogen oxides (NOx).
“Near Zero-Emissions”: EPA and CARB Certified a Heavy-Duty Natural Gas Engine to 0.02 g Standard In September 2015, the U.S. Environmental Protection Agency (EPA) and the California Air Resources Board (CARB) certified the world’s first heavy-duty engine that emits oxides of nitrogen (NOx) at levels so low they are considered “near-zero” (0.02g NOx/bhp-hr). This is the cleanest commercially available heavy-duty truck engine available in the market today, offering the ability to reduce emissions 90% below even the most stringent U.S. EPA standards.
Today's natural gas engines offer a 90% NOx reduction over the EPA’s strictest
emission standards, making them the
cleanest commercially available technology
The “Game Changer” report shows that “Near-Zero” NGVs are cleaner than “Zero-Emission” All-
Electric trucks
NGVs Have Lower NOx Emissions Than All-Electric Trucks The emission benefits of the new “Near-Zero” engine are well documented in the 2016 Game Changer report issued by Gladstein, Neandross and Associates (GNA)1. The GNA report indicates that a truck or bus equipped with a natural gas engine that has been certified to the 0.02 g/bhp‐hr Optional Low NOx Standard has tailpipe NOx emissions that are comparable to – or possibly lower than – the amount of NOx emitted to produce electricity used to charge a comparable heavy-duty All-Electric Truck.
1 Gladstein, Neandross & Associates, Game Changer Technical White Paper (2016) http://ngvgamechanger.com/, Section 6.4 and Appendix 1. Emissions of low‐NOx natural gas engines produce NOx emissions that are comparable to or lower than similar electric drive vehicles in all 50 U.S. states when considering upstream NOx.
Critical Insight: Study Finds that Natural Gas Engines Outperform Diesel Engines in Real World Situations Natural gas (NG) engines today meet an optional Low NOx standard
that is ten times cleaner than the standard required for new diesel
and natural gas engines. However, the in-use emission benefits of NG
engines could be even more significant.
A recent report published in Environmental Science and Technology2,
evaluated in-use emissions of earlier model year NG vehicles and
found that NG engines performed much better in real world
conditions (i.e., operating within city limits in low-speed, high-idling
situations), registering NOx levels that were 96% lower than levels
produced by tested diesel engines equipped with the latest
emissions controls. The study found that diesel NOx emissions
operating in similar conditions produced emissions that were 5 -7
times higher than in-use certification limits in some cases.
Related Recommendations for EMT Funding
✓ Provide a higher level of funding for technologies that are proven to exceed federal emission
levels for nitrogen oxides ▪ Vehicles with engines certified to California’s Optional Low‐NOx Standard should receive the highest
level of funding (e.g., 25% in the case of private sector vehicle replacements)
▪ Use the state's approved DERA plan to fund low-NOx natural gas trucks (i.e., 35% of the replacement
cost for private vehicles equipped with low-NOx engines)
✓ Provide the highest level of funding to applications that will reduce the largest share of NOx
emissions ▪ Evaluate the main mobile source(s) of NOx emissions in urban and non-attainment areas (Note: In
most regions, this means prioritizing funding for short-haul, regional-haul, and refuse trucks)
▪ Do not segment the funding – fund the projects that best achieve the most NOx reductions

2. Responsible: NGVs Extend the Funding and Foster Economic Development
❖ Key Point: NGVs are far more cost-effective in delivering emission reductions than other
alternative fuel options, such as hybrid and electric vehicles.
Due to lower fuel and maintenance costs, NGVs offer an 18 to 24 month
payback. As production increases and fuel tank prices come down, vehicles
will become less expensive and enjoy a shorter payback period
NGVs Offer a Fast Return on Investment While NGVs typically cost more than gasoline or diesel vehicles upfront (largely due to the cost of high-pressure and insulated fuel tanks which are necessary to store CNG or LNG), owners and operators of high mileage vehicles typically see a pay back in as little as 18–24 months. This is due to:
Lower Fuel Costs: Natural gas fuel is currently $0.50 to $1.00 less per gallon. The savings in fuel costs can translate into significant savings over the life of a vehicle, depending on fuel efficiency and the number of miles driven. The greatest savings are currently being seen in heavy-duty, high mileage fleets.
Lower Maintenance Costs: NGVs are easier and cheaper to maintain than diesel trucks because they have:
o No diesel particulate filter (DPF) o No DPF regeneration or waste disposal o No selective catalytic reduction (SCR) o No diesel emission fluid (DEF)
High-profile fleets across the U.S. are using natural gas vehicles in their everyday operations, transporting
passengers, and hauling waste, packages, beverages, and other goods
NGVs Have Been Road-Tested by Leading Fleets There are more than 160,000 NGVs on U.S. roads today, spanning all
weight classes and vehicle applications. The adoption of NGVs has been
pioneered by several high-profile fleet operators, including UPS,
Anheuser-Busch, Kroger, FedEx, Frito Lay, Waste Management, LA
Metro, all of which performed exhaustive analysis to determine the best
vehicle and fueling options for their fleet based on application, range,
duty cycle, and payload.
Given the significant fuel and emission reductions realized by early
adopters, the popularity of NGVs has continued to build in the U.S., with
20% of all U.S. transit buses now running on CNG or LNG, 35 airports
operating NGVs in their private fleets or championing policies that
encourage use by private fleets, and more than 50% of new refuse trucks
running on natural gas.
To fuel these vehicles, natural gas infrastructure is rapidly expanding
with more than 1,640 CNG and 123 LNG fueling stations operating today.
5
Dollar-for-Dollar Natural Gas Delivers Greater Numbers of Total Vehicles and Greater Total Tons of NOx Emission Reductions This is illustrated by the chart below which looks at several different funding options for natural gas and electric
vehicles including providing 100% of the cost of new, replacement vehicles for public fleets, using the maximum
funding levels specified in the settlement for natural gas and electric vehicles purchased by private fleets, or funding
only the incremental cost of new, replacement vehicles. In each case, the deployment of natural gas vehicles (e.g.,
regional haul trucking, refuse trucks, and transit buses) will provide the most NOx emissions reduction to comply with
the EPA’s latest national ozone standards.
Chart: Heavy-Duty Truck Deployment & NOx Reduction Comparisons Under Different Funding Scenarios
Critical Insight: Comparable All-Electric Vehicles Cost 2-3x More Than an NGV While actual cost depends on the application, an all‐electric medium- or heavy‐duty vehicle usually costs two to three times the amount of a comparable vehicle powered by a 0.02 g NOx natural gas engine. As noted above, funding heavy-duty NGVs delivers greater emission reductions than similar projects involving all-electric trucks, and they offer the best ability to reduce emissions on a large scale because the funding will extend further.
6
Related Recommendations for EMT Funding
✓ Ensure that funding incentivizes adoption by both public and private fleets ▪ While it might be tempting to fund public vehicles at the 100% level, this will limit the total number of
deployed vehicles and therefore lessen the overall emission reductions
▪ Funding levels should be large enough to offset the incremental cost of new, cleaner vehicles, as well
as to address the fact that replaced vehicles must be scrapped
✓ Prioritize funding for clean vehicles rather than fueling infrastructure ▪ Funding should be used to incentivize fleets and vehicle acquisitions where existing fueling
infrastructure exists to better support investments that have already been made
▪ If fueling infrastructure needs to be developed, funding should be secured as part of private-
public partnerships. Using the funding in this way will encourage additional economic
development in the state and increase the availability of stations for future deployments
3. Available: NGVs Meet the Diverse Operating Requirements of Every Fleet Application
❖ Key Point: Dozens of models of medium- and heavy-duty low-emission natural gas vehicles and engines are
commercially available from reputable, world-known OEMs with established sales and service networks.
Wide Array of NGV Options Commercially Available There are many natural gas vehicle options available from several original equipment manufacturers (OEM). These vehicles can be purchased from the dealership through a process that has been streamlined for the customer. Many other medium- and heavy-duty vehicle options are available through small vehicle modifiers (SVM). These companies manufacture conversion systems that have been certified and approved by the U.S. Environmental Protection Agency and/or the California Air Resources Board. These approved systems can be installed on new and used vehicles to run on natural gas.
Additionally, Cummins Westport currently offers the 6.7L ISB-G, 8.9L ISL-G and the 11.9L ISX-G natural gas engines. These spark-ignited engines are used in a variety of applications, including refuse trucks, transit buses, cement trucks, short- and regional-haul tractors, delivery trucks, school buses, and shuttles. Roush offers a school bus engine that is certified to the Low-NOx standard of 0.10. Retrofit and repower options are also available from a variety of manufacturers. For a full list of EPA and CARB certified engines, visit www.ngvamerica.org/vehicles/vehicle-availability. A list of available NGV manufacturers and conversion companies follows.

Critical Insight: Heavy-Duty Electric and Fuel Cell Vehicles are Not Commercially Available
As of today, three unique fuel-technology combinations hold the most promise to successfully transform America’s HDV transportation sector to zero and near-zero emissions:
1. Near-zero-emission internal combustion engines fueled by conventional or renewable natural gas
2. Zero-emission battery-electric-drive systems 3. Zero-emission hydrogen fuel cell systems
While battery-electric and hydrogen fuel cell systems can offer extremely low emissions profiles, the lack of commercially available heavy-duty and limited medium-duty products and charging/fuel distribution networks makes implementation in the near future impractical or very difficult. Furthermore, these vehicles are being developed by niche, start-up companies and have only been used in early test programs; comparatively, medium- and heavy-duty NGVs from major OEMs have been widely, commercially available in dozens of applications for over two decades. Near-zero-emission internal combustion engines fueled by conventional or renewable natural gas are the only option to immediately and cost-effectively provide extremely low NOx and GHG emissions in high-impact HDV sectors.
Related Recommendations for EMT Funding
✓ Prioritize funding for commerically available products ▪ Given that the NOx emissions from Volkwagen vehicles are already in the air, funding should be
concentrated to projects that allow us to deploy the cleanest vehicles available today (i.e., not pre-
commercial or research and development projects)
✓ Scale funding to incentivize the cleanest engines available ▪ Provide greater funding for medium- and heavy-duty engines that deliver NOx reductions over and
above what is currently required for new diesel vehicles
▪ Given that the EMT was created because of NOx pollution associated with non-compliant diesel
vehicles, we believe that the funding should be set aside for clean, alternative fuel vehicle projects and
should not be used to fund more diesel fueled vehicles

NGVAmerica and its members are eager to serve as a resource to assist ADEQ in their evaluation and development of
the state’s Beneficiary Mitigation Plan. We strongly encourage Arkansas to recognize the superior and unmatched
role that natural gas vehicles can play in delivering nitrogen oxide (NOx) emissions reductions required by the
settlement and Trust.
